serious personal injury in a crash.
• Always carefully follow the child restraint manufacturer's
instructions for proper installation and use of child restraint
systems.
& WARNING (continued)
• Never use the LATCH or tether anchorages to attach safety
belts or other kinds of occupant restraints.
• Child restraint tether attachments and lower attachments are
only designed to secure a child restraint that has been equipped
to use these anchorages.
• Tether anchorages and lower anchorages are designed to with­
stand only those loads imposed by correctly fitted child restraints.
Under no circumstances can they be used safely for adult or child
safety belts or harnesses.
• Never mount more than one child restraint to a single tether or
to a lower anchorage point. Attaching two child restraints to a
single anchorage point can cause the anchorage to fail and cause
serious personal injury in a crash.
0 Note
• Remove the guidance fixtures before folding the rear seatback to
prevent damaging the seat cushion.
• If you leave the guidance fixtures installed for several days, they
could leave a mark on the upholstery on the seat cushion and back­
rest in the area that the guidance fixtures were installed. The uphol ­
stery would also be permanently stretched around the guidance
fixtures . This applies especially to leather seats.
[ i] Tips
• Always remove the guidance fixtures when not in use .
• Please keep the guidance fixtures in a safe place with the vehicle
when not in use. •

Using tethers on rear-facing child restraint
systems
Currently, few rear-facing child restraint systems come with a tether.
Please read and heed the child restraint system manufacturer's
instructions carefully to determine how to properly install the
tether.
& WARNING
A child in a rearward -facing child safety seat installed on the front
passenger seat will be seriously injured and can be killed if the
front airbag inflates -even with an Advanced Airbag System.
• The inflating airbag will hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest, center arm rest, or door .
• A tight tether or other strap on a rearward-facing child restraint
attached to the front passenger seat can put too much pressure
on the weight-mat in the seat and register a heavier weight in the
Advanced Airbag System. The heavier weight registered can make
the system work as though an adult were on the seat and deploy
the Advanced Airbag when it must be suppressed causing serious
or even fatal injury to the child.
• If you must install a rearward facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not come on and stay on,
& WARNING (continued)
immediately install the rear-facing child safety seat in a rear
seating position and have the airbag system inspected by your
Audi dealer .

Notice about data recorded by
vehicle control modules
Your vehicle is not equipped with an Event Data Recorder (EDRl,
installed by some manufacturers for the express purpose of
capturing data for retrieval after an accident or crash event . EDR's
are sometimes called "crash recorders".
Some state laws restrict the retrieva l or downloading of data stored
by EDR's that were insta lled in a vehicle for the express purpose of
retrieving data after an accident or cras h event without the owner's
consent.
Although your vehicle is not equipped with an EDR, it is equipped
with a number of electronic control modules for various vehicle systems such as, for example, engine function, emission contro l, as
we ll
as for the a irbags and safety belts.
These electronic control modules also record vehic le-related data
dur ing norma l ve hicle opera tion for diagnost ic and repair purposes .
The recording capacity of the electronic control modules is limited
t o data (no sound is recorded) and only a small amount of data is
actua lly recorded over a very limited period of time and stored when
a system fault or other condition is sensed by a control unit. Some
of the data then stored may relate to vehic le speed, d irection,
braking as we ll as restraint system use and performance in the
event of a crash o r other condition . Stored data can only be read and
downloaded with special equipment. •
Electronic Stabilization Program (ESP)
General information
The ESP improves the vehicle stability.
I~
" "'
( ~ 1~ IA I 3-)
Fi g. 25 4 Cen ter
co nso le w it h ES P
sw itch
ESP is designed to he lp you maintain vehic le control in situations
where the car approaches the limits of "grip", especia lly when
acce lerating and cornering . ESP reduces the risk of skidding and
improves stabil ity under al l road conditions.
T he system operates across the entire speed range in combination
with the ABS system. If the Ant i-Lock Brake System (ABS) malfunc­
tions, the ESP wi ll also shut down .
How the syste m w ork s
The Anti -Lock Brake System (ABS), Electronic Differential Lock (EDU
and the Anti-Sl ip Regulation System (ASR) are integrated in the e lec­
tronic stabi lization program. In addition to the data provided by
t hese functions, the ESP control unit requires additional measure ­
ment data provided by high performance sensors . The rotational
speed of the veh ic le about its vertica l axis, the lateral acce lerat ion
acting on the vehicle, the brake pressure and the steering angle are
a ll measured . _,,,,
